The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

The embodiment of the utility model provides a sealing cover for a clutch liquid storage chamber, which is used to seal the liquid storage chamber 110 on the clutch 100. Referring to Figures 1 and 8, the embodiment of the utility model provides a sealing cover for a clutch liquid storage chamber, comprising a frame 1, a sealing layer 2 and a mounting portion 3, wherein the frame 1 has a groove 15 with an opening 14 facing upward; the sealing layer 2 at least covers the outer surface of the frame 1; the mounting portion 3 is arranged at the bottom of the frame 1 and at the junction of the side and the bottom of the frame 1, and the mounting portion 3 is arranged to protrude from the outer surface of the sealing layer 2 and can be interference-fitted with the mounting groove of the liquid storage chamber 110.

The frame 1 is coated with a sealing layer 2, which can play a supporting role, improve the strength and stability of the sealing cover, and prevent the sealing cover from being easily deformed and damaged under pressure; when in use, since the frame 1 is provided with a groove 15, the sealing tool is matched with the groove 15 for positioning, and then the sealing cover is aligned with the installation groove of the liquid storage chamber. The operator presses the sealing tool to make the sealing layer 2 and the installation groove of the liquid storage chamber 110 interference fit, thereby sealing the liquid storage chamber 110 to prevent coolant leakage. The groove 15 design of the frame 1 is easy to position, and at the same time, it can also save materials and achieve lightweight.

Referring to Figures 2 and 3, the size of the skeleton 1 should depend on the size of the mounting groove of the liquid storage chamber 110 to be sealed. Generally speaking, the size of the skeleton 1 is preferably slightly smaller than the size of the mounting groove, so that after the outer layer of the skeleton 1 is covered with the sealing layer 2 and the mounting portion 3, the overall size of the sealing cover is slightly larger than the mounting groove, so that the two can fit tightly and the sealing effect is good. The sealing cover will not be too small, resulting in poor sealing effect and coolant leakage; nor will the sealing cover be too large, resulting in inability to be assembled with the mounting groove.

Since the installation slot of the liquid storage chamber 110 extends in an arc shape and the arc is less than 360 degrees, in order to ensure that the sealing cover and the installation slot are completely matched, the shape of the frame 1 should be basically consistent with the shape of the installation slot. Referring to Figures 2 and 3, in this embodiment, the frame 1 extends in an arc shape, and the frame 1 has two positioning ends 13, and an opening 14 is formed between the two positioning ends 13.

Specifically, the line connecting one positioning end 13 and the center of the frame 1 is a first straight line, the line connecting the other positioning end 13 and the center of the frame 1 is a second straight line, and the angle between the first straight line and the second straight line is greater than or equal to 30 degrees and less than or equal to 90 degrees. It is only necessary to ensure that the size of the opening 14 of the frame 1 is consistent with the size of the opening 14 of the positioning groove. By setting different angles, the sealing cover can better adapt to the installation requirements of different clutches 100, so that it can be used for a variety of different types of clutch 100 systems, reducing the complexity of production and installation.

Referring to Fig. 4 and Fig. 5, regarding the specific structure of the skeleton 1, the skeleton 1 includes a bottom plate 11 and a side plate 12, the side plate 12 is arranged in a ring around the circumferential edge of the bottom plate 11, the mounting portion 3 is arranged at the bottom of the bottom plate 11 and at the junction of the side plate 12 and the bottom plate 11, and the bottom plate 11 and the side plate 12 surround a groove 15. In this embodiment, the skeleton 1 is processed by a stamping process, and the bottom plate 11, the side plate 12 and the groove 15 are integrally formed, which is convenient for processing and production, and the integral forming has good stability. In some embodiments, the bottom plate 11 and the side plate 12 can also be processed separately, and then assembled by welding.

Specifically, the side plate 12 extends in a direction perpendicular to the bottom plate 11, and the height of the side plate 12 is less than the depth of the mounting groove, thereby ensuring that the frame 1 does not protrude from the mounting groove, and fits well with the mounting groove, and has high stability; at the same time, it can prevent the frame 1 from protruding from the mounting groove from interfering with the installation and operation of other parts in the clutch 100.

As mentioned above, the skeleton 1 extends in an arc shape, so the bottom plate 11 extends in an arc shape. Specifically, the bottom plate 11 includes a side edge 111 and an end edge 112, and the two end edges 112 form a positioning end 13, and the side plate 12 located at the end edge 112 extends in an arc shape. Since the two ends of the installation groove extend in an arc shape, the side plate 12 located at the end edge 112 also extends in an arc shape, which improves the fit between the skeleton 1 and the installation groove and improves stability. At the same time, the arc-shaped side plate 12 can improve safety and avoid the tip from scratching the staff during assembly. Among them, the longer side of the bottom plate 11 is the side edge 111, the shorter side of the bottom plate 11 is the end edge 112, and the above-mentioned opening 14 is between the two end edges 112.

Since both ends of the mounting groove extend in an arc shape, in order to improve the sealing performance of the sealing cover, the mounting portion 3 located at the end edge 112 extends in an arc shape. This ensures that the mounting portion 3 can fit into the mounting groove, improves the sealing performance, and at the same time, makes the sealing cover more stable after assembly and less likely to fall off. In addition, the arc-shaped end edge 112 can reduce the risk of stress concentration. Sharp corners or edges may cause stress concentration, thereby reducing the durability of the mounting portion 3. The arc-shaped end edge 112 can evenly distribute stress and increase the life of the mounting portion 3.

Referring to Figures 6 and 7, in this embodiment, the mounting portion 3 is integrally formed with the sealing layer 2. Specifically, the sealing layer 2 and the mounting portion 3 are generally made of flexible materials such as rubber and silicone, and are generally coated on the outer layer of the skeleton 1 through a vulcanization process, which is convenient for processing and production, and the finished product is stable and not easy to fall off. It can be understood that the vulcanization process is a common technical means in the field and is not described here. In some embodiments, the sealing layer 2 and the mounting portion 3 can also be processed separately, and the mounting portion 3, the sealing layer 2 and the skeleton 1 are connected by bonding.

Regarding the coating position of the sealing layer 2, the sealing layer 2 can be coated only on the outer surface of the skeleton 1, or on the outer surface and the inner surface of the skeleton 1. It is only necessary to ensure that the outer surface of the skeleton 1 is coated with the sealing layer 2 to achieve a sealing effect. In this embodiment, the sealing layer 2 covers the outer surface and the inner surface of the skeleton 1. Since the sealing layer 2 is integrally formed by a vulcanization process, the sealing layer 2 is coated on the outer surface and the inner surface of the skeleton 1 for easy processing and production. At the same time, the integral molding makes the sealing layer 2 have no bonding points or seams, which can prevent air from entering the sealing layer 2 and causing it to crack, so that the sealing layer 2 can withstand high pressure and high temperature environments, thereby increasing the service life of the sealing layer 2. In some embodiments, when the sealing layer 2 is processed separately and connected by bonding, in order to save materials, the sealing layer 2 can be coated only on the outer surface of the skeleton 1.

In order to facilitate positioning and installation, a plurality of limiting holes 21 are provided on the outer surface of the sealing layer 2 on the outer side of the frame 1, and a limiting block is provided on the inner wall of the installation groove, and the limiting block can be engaged with the limiting hole 21. In this embodiment, a plurality of limiting holes 21 are provided at intervals along the circumferential direction of the sealing layer 2, and a limiting block is provided on the inner wall of the installation groove corresponding to each limiting hole 21. By engaging the limiting holes 21 with the limiting holes 21, positioning and assembly are facilitated, and assembly efficiency is improved; at the same time, in the high-pressure or high-vibration environment of the clutch 100, the limiting holes 21 can prevent the sealing cover from being misplaced or moved, and can improve the stability of the sealing cover.

When installing the sealing cover for the clutch fluid storage chamber provided by the embodiment of the utility model, first assemble the positioning tool into the groove 15, then align the sealing cover with the installation groove, and at the same time, align the limiting hole 21 on the sealing layer 2 with the limiting hole 21 on the inner wall of the installation groove, press the positioning tool to make the sealing cover and the installation groove have an interference fit, and then remove the positioning tool. In some cases, it is also possible not to use the positioning tool, align the sealing cover with the installation groove, and at the same time, align the limiting hole 21 on the sealing layer 2 with the limiting hole 21 on the inner wall of the installation groove, and assemble it by directly pressing the groove 15 of the sealing cover.

The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
